CHARGER FOR GAS-PRODUCERS.

SPECIFICATION forming part of Letters Patent No. 746,591,`dated December 8, 1903.

Application ined July 14, 1902.

To all whom. t may concern.' l

Be it known that I, GEORGE SIEURIN, a citiv` zen of the United States, residing at'Worcester, in the county of "Worcester and Commonwealth of Massachusetts,have inventeda new and useful Improvement in Gas-Producers, of which the following is a specification, accompanied by drawings forming a part of the same, in Whichf Figure 1 represents a vertical sectional view through the feeding mechanism ofthe gasproducer. Fig. 2 is a plan view of the coal-V distribu ter removed fromthe producer. Fig. 3 is a sectional View on line 3 3, Fig. 1. Fig. 4 I5 is a plan View of the coal-agitator removed from the producer. Fig. 5 is a planwiew of. the coal-distributer, partly-shown in section by the removal of the conical'plates A, which' cover the coal-openings, in order to disclose zo the outer edge of the coal-distributing plate.- Fig. 6 is a detached vview of a -portion ofthe coal-distributer shown in vertical sectional view; and Fig. 7 is a vertical sectional View y similar to that 'shown in Fig. .1, but showing a modification in the construction;

Similar reference letters and figures refer to similar part-s in the dierent views.

My present invention relates to the feeding mechanism of a gas-producer by which fuel '3o is supplied to the heating-chamber; and it has for its object to accomplish a saving in fuel and labor, to increase the efficiency of the producer' by securing a uniform supply of coal uniformly distributed throughout the heating-chamber, and to provide means for protecting those parts of the feeding mechanism which are exposed to heat and for preventing the escape of noxious gases from the feeding mechanism.

My improved feeding mechanism as represented inthe accompanying drawings coinprises a coal-hopper, a stationary coal-reservoir, a stationary coal-distributer for evenly distributingthe coal in the producer, and a coal-agitator interposedbetween the distributer and the reservoir, towhich an oscillating or shaking motion or a continuous rotary motion is imparted, as desired; and my invention consistsV in the employment in the 5o feeding mechanismpof a gas-producer of a Serial No. 115.401. (No model.)

stationary distributing-plate of varying diameter, whereby the supply of coal to the pro- 6o Referring to the accompanying drawings,

`1 1, Fig.' 1, denote the upper part of the side walls of the heating-chamber, upon which is supported a top plate 2, having a central opening 3, provided with an upstanding flange 4 and a concentric outeriiange 5, with a waterspacez 6 inclosed between .the flanges 4 and 5. Supported upon .the upper edge ofl the inner flange 4 and extending over the central opening 3 ofthe top plate is al coal-distributer. 7o (Shown in plan View in Fig. 2 andavertical sectional view in Fig. 1 and partly showniin Figs. 5 and 6.) The coal-distributor consists of twoinverted pan-shaped'sections-an outer section 7 and an inner section 8. The outer 75 section 7 is supported by its horizontal edge 9 upon the upper edge of the iiange 4 of the top plate 2,' and from the edge 9 an annular flange 10 projects downwardly into the water inclosed in the water-space 6. The outer and 8o inner pan-shaped sections 7 and 8 are connected by the hollow radial arms ll', inclosing water-passages between the sections 7 and 8,

so that Water delivered in the outer section 7 may flow freely through the hollow arms 11 85 into the inner pan-shaped section 8, as shown in Fig. 5, alternating with the hollow arms ll 11. The outer section 7 is provided with arc-shaped inclined portions A A, between which and the sections l2, 13, 14, and 15 the 9o coal passes to the heating-chamber. Between each of the hollow arms l1 the periphery of the inner section 8 is formed in sections of varying inclination, four such sections `12, 13, 14, and l5 being formed between each of 95 the hollow arms 1l, the inclined sections 12, 13, 14, and 15 forming the distributing-surface over which the coal delivered from the reservoir slides into the heating-chamber of the producer. As each of the sections l2, 13, roo

14,-and 15 are of varying inclination from a perpendicular, the lower ends of the sections are consequently at different radial distances from the center, and the coal sliding over each of these inclined sections will therefore be delivered in the heating-chamber at different radial distances from the center.

Although I have shown but four inclined surfaces between each of the radial arms 11, the number and inclination may be varied as desired to accomplish the proper distribution of the coal within the heating-chamber.

The inner section 8 of the coal-distributer is provided with a central hub 16, which forms a bearing for the lower end of a rotating shaft 17, to which is attached the long hub 18 of the coal-agitator 19, (shown in plan view in Fig. 4,) and consisting of a circular curved disk 20, forming a cover for the central pan -shaped section 8 of the coal-distributer. Extending from the side of the hub 19 and radially across the upper surface of the disk 2O are ribs 21, which serve to disturb the coal resting upon the disk as the agitator is moved. Attached to the disk 20 by arms 22 is a bent plate 23, to which mechanism for moving the agitator is operatively connected, said mechanism consisting in the present instance of a rocking shaft 24, having at one end a radial arm 25, connected with an eccentric 26, by which the shaft is rocked, and upon its opposite end a radial arm 27, pivotally connected by a link 28 with the bent plate 23, the rocking motion of the shaft 24 imparting an oscillating motion to the agitator 19. The arms 22 22 work back and forth in a slot 51, formed in the upper inner edge of the section 7.

The outer section 7 of the coal-distributer is provided with three notched ribs 29, Fig. 2, upon which rests the iaring ange 30 of the coal-reservoir 31, provided with a hoppershaped bottom 32, having a central opening 33 for the delivery of coal upon the disk 20 of the agitator. The opening 33 is preferably surrounded by a depending serrated iiange 34. The hopper-shaped bottom 32 is provided with a spider 35, supporting a hub 36, in which the shaft 17 is journaled, the shaft 17 and the attached coal-agitator 19 being suspended by means of a collar 37, attached to the upper end of the shaft and resting upon the hub.

In Fig. 7 I have shown a slight modification in the construction of the feeding device, which consists in extending a horizontal plate or cover 38 from the upper end of the hub 16, and at its outer edge I form awater-space 39 to receive the iian ges 40 of the coal-reservoir, which is supported at 41 upon the upper edge of aconcentric ange 42, raised upon the horizontal plate 38 instead of being supported y upon the notched ribs 29, as shown in Fig. 1.

In Fig. 1 the iiange 30 of the coal-reservoir is water-sealed in the outer pan-shaped section 7 of the distributer, while in Fig. 7 the corresponding ange 40 is sealed in the waterspace 39.

Water may be supplied to the water-space 6 by means ofl the overflow from the space between the sections 7and 8, and a dischargepipe 43 is provided leading from this space 6, the opening being surrounded by an imperforate wall 50. In Fig. 1 I have shown a connection 44, carried by the flange or apron 30 of the coal-reservoir and communicating with the space between the sections 7 and 8, the connection having a water-supply pipe 45 secured thereto. The coal-reservoir is closed at its upper end in any convenient manner, as by means of a bell 46, connected with a counterweight (not shown) by means of a lever 47, and the water-space 6 is provided with a series of conical openings 48, adapted to be closed and sealed by means of covers 49.

The operation, briefly set forth, is as follows: The coal-reservoir is charged with the coal and the agitator 2O set in motion, the lowermost layers of coal resting upon the agitator-disk and being displaced therefrom by the motion of the disk. The coal falls o the edge of the disk onto the outer surfaces of the various inclined sections 12, 13, 14, and 15 and passes downward upon the inclined sections and inclosed by the arc-shaped inclinations A A and falls off of the unequal ends of the Various sections 12, 13, 14, and 15 to the heating-chamber below.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination with the heating-chamber of a gas-producer provided with an opening in its top, of a stationary coal-distributer located within said opening and provided with a series of coal-distributing surfaces of varying inclination from avertical plane symmetrically arranged around said distributer.

2. The combination with the heating-chamber of a gas-producer provided with an opening in its top, of a coal-distributer extending across said opening and comprising two panshaped sections with openings between said sections for the delivery of coal to the heating-chamber.
